Answer:
The number of follower after x years is 40,000
Step-by-step explanation:
Given as :
The number of current followers = p = 40,000
The rate of growth of follower = r = 2.5%
The time period of growth = t = x years
Let The number of follower after x years = A
<u />
<u>Now, According to question</u>
The number of follower after x years = number of current followers ×
Or, A = p ×
Or, A = 40,000 ×
Or, A = 40,000 ×
So, The number of follower after x years = A = 40,000 ×
Hence, The number of follower after x years is 40,000 Answer
Answer:
793 liters of washing fluid is needed
Step-by-step explanation:
step 1
Find the slant height of the triangular faces of pyramid
we know that
The lateral area of a square pyramid is equal to the area of its four triangular faces
so
where
b is the base of triangle (is the same that the length of the square base)
l is the slant height
To find out the slant height we need to apply the Pythagorean Theorem
so
we have
substitute
step 2
Find the lateral area of the pyramid
we have
substitute
step 3
Find out how much window washing fluid is needed
we know that
2 L of washing fluid cover 5 square meters
so
using proportion
Round up
793 liters of washing fluid is needed
The principal value is $150.
We have the following values -
rate of interest - 4%
Time period = 6 months = 0.5 year
Simple interest = $36
We have to find the principal value.
<h3>What is the formula to calculate the Simple Interest for a Principal amount of $P at a rate of r% per annum for time of t years?</h3>
The simple interest can be calculated using the formula -
S.I. =
The above expression can be written in terms of principal value as -
We can use the above formula in the question given - Using the formula for principal value we get -
P =
P =
P = $1800
Hence, the principal value is $150.

Answer:
y=2x+3 is non-proportional. y=5x is proportional.
Step-by-step explanation:
y=2x+3 is not proportional because there is the +3. also, when it is graphed on a graph, the line does not pass through the origin/zero.
y=5x is proportional because it does not have any other values attached to the y value. when it is graphed, the lie goes through the origin/zero.
